socket新人,求解

C/C++ code

#include <iostream>#include <winsock2.h>using namespace std; /****求完整的一个程序****/int main(){    WSADATA wsaData;    int ret;    if((ret = WSAStartup(MAKEWORD(2, 2), &wsaData)) != 0)    {        cout << "Error_Error_" << ret << endl;        return 0;    }    if(WSACleanup() == SOCKET_ERROR)    {        cout << "Error_Error_" << WSAGetLastError() << endl;    }    SOCKADDR_IN sockAddr;    sockAddr.sin_family = AF_INET;    INT port = 5055;    sockAddr.sin_port = htons(port);    //这个inet_addr不能把char*转换成unsigned long类型么????    sockAddr.sin_addr = inet_addr("127.0.0.1");}/**************************************************错误**************************************************//*error C2679: 二进制“=”: 没有找到接受“unsigned long”类型的右操作数的运算符(或没有可接受的转换)**//*microsoft sdks\windows\v6.0a\include\inaddr.h(34): 可能是in_addr &in_addr::operator =(const in_addr &)/

[解决办法]
sin_addr.s_addr = inet_addr("127.0.0.1");
